Last modified

CVE-2026-86424 is a low-severity vulnerability rated 2.5/10 on the CVSS scale. ImageMagick before 7.1.2-30 and 6.9.13-55 contains a time-of-check-time-of-use (TOCTOU) vulnerability in the video decoder that allows attackers to bypass path policy write restrictions via symlink swaps. An attacker can replace a symlink between policy validation (check-time) and the file write operation (use-time) to write to policy-denied locations.. EPSS estimates a 0.12% chance of exploitation in the next 30 days.
